● Filter paper: oil filter has higher requirements for filter paper than air filter, mainly because the temperature of engine oil varies from 0 to 300 degrees. Under severe temperature changes, the concentration of engine oil also changes accordingly, which will affect the filtering flow of engine oil. The filter paper of high-quality oil filter should be able to filter impurities under severe temperature changes while ensuring adequate flow.

Rubber sealing ring: The filter sealing ring of high-quality engine oil is made of special rubber, ensuring 100% non oil leakage.

● Backflow inhibition valve: only available in high-quality oil filter. When the engine is stopped, it can prevent the oil filter from drying; When the engine is ignited again, it immediately generates pressure and supplies oil to lubricate the engine. (also known as check valve)

● Overflow valve: only available in high-quality oil filter. When the external temperature drops to a certain value or when the oil filter exceeds the normal service life, the overflow valve will open under the action of special pressure, allowing unfiltered oil to flow directly into the engine. Despite this, impurities in the oil will enter the engine together, but compared to the damage caused by the absence of oil in the engine, such damage is much smaller. Therefore, the overflow valve is the key to protecting the engine in emergency situations. (also known as bypass valve)
